Abstract: A sensor package and a display device are provided. The sensor package is disposed inside the display device. The sensor package includes a substrate, a plurality of sensor elements, a shielding cover, a first polarizer, and a second polarizer. The plurality of sensor elements and the shielding cover are disposed on the substrate. The shielding cover covers the plurality of sensor elements. When light passes through the first polarizer, the light forms a first polarized light beam. When another light passes through the second polarizer, the another light forms a second polarized light beam. A first polarization direction of the first polarizer is different from a second polarization direction of the second polarizer.

Abstract: The present disclosure relates to an optical sensing module, a system and a method for operating the optical sensing system. The optical sensing module includes a light emitter that emits a sensing light in a specific wavelength range and a photodiode unit. The photodiode unit includes a first photodiode used to sense a first wavelength light, a second photodiode used to sense a second wavelength light, and a third photodiode used to sense a third wavelength light. The optical sensing module implements a proximity sensor by operations of the second photodiode and the third photodiode, or a biometric sensor by operations of the first photodiode, the second photodiode, and the third photodiode. The photodiode unit receives a reflected light from an object to be detected so as to determine if the object is proximal, and then determine whether or not the proximal object is human skin.
